Ho Drawing.-

To all whom it may concern:

Be it known that I, DAGMAR H. RnmuL- Cementing Compositions, of whichthe following is a specification.

My invention relates to a composition of matter for mending articles ofaluminum, copper, brass, iron, agate galvanized and tin ware, such askitchen utensils or the like or metal articles of any kind in which itmay be necessary to close up leaks or cracks or the like therein.

One of the objects of my invention is to provide a cement which can beeasily applied, which will assume suflicient hardness so as not to comeoff of the articles cemented therewith.

Another object is to provide a cement which will not become brittle andcrack while the repaired articles are in use and which will look well onthe same.

Other objects will appear fromthe subjoined specification and claims.

In carrying out my invention I prepare a composition by mixingtogether-asbestos,

preferably such as has been previously shredded, oxid of zinc, black endof manganese, china clay, aluminum powder, varnish and linseed oil.

These ingredients are preferably mixed in the following proportlonsmeasured by volume:

8 parts of asbestos.

4e'parts of oxid of zinc.

4 parts of black oxid of manganese.

3 parts of china clay.

6 parts of aluminum powder.

A liquid consisting ,of one-half varnish and one-half'linseed oil.

The above named uantities of asbestos,

- oxid of zinc, black oxi of manganese, china clay and aluminum powderare preferably arranged in layers upon one another and are then mixedwith the above mentioned quan- I in diameter tities of varnish andlinseed oil until the mixture assumes the consistency of a good putty.Suitable portions of this mixture are then taken and may then beconveniently rolled into sticks about one third of an inch by means ofa' flat wooden paddle;

In using the said compiefition for example for the purpose-of men g akitchen utensil, such as e pot, which has a'hole in it, I proceed in thefollowing manner:

Specification ofLetters Patent. P t t d June 11, 191 Application filedJanuary 28, 1918. Serial No. 213,415.

The end of the above mentioned stick is heated in a suitable manner byany convenient means to such a degree that it ma be readily handled whenso heated. A sma l quantity of the same is then pinched oil and rolledbetween the fingers. It is then pushed through the hole to be closed,one finger being held on one side and another. finger on the other sideso that the portion of the composition taken is flattened out on bothsides. It is then heated for about ten minutes in order to bake it. Whenit is baked hard a little water is poured into the mended utensil and itis allowed to boilfor a few minutes. After the utensil has cooled down,the mending process is finished.

The asbestos is used for the purpose of utilizing its fireproofqualities and for holding the other ingredients together, after the. Ymixture has been baked. The purpose 0f the china clay is to provideamaterial which bakes quicker and harder than any of the otheringredients and the oxid of zinc and the black 0nd of manganese form acombination which make the composition very strong and resistant towear.- The aluminum powder is added for the purpose of giving thecomposition the color of aluminum so that it looks well after beingapplied to the articles mended therewith. The varnish is usedas avolatile binder to hold the said other ingredients together beforebaking and the linseed oil serves the purpose of a preservative agentbefore the cement is used.'-

It is understood that I do not limit myingredients of my cementenumerated above, as at is obvious that the percentage ofthe variousIngredients comprised therein may- .be varied within reasonable limitswithout departing from the spirit of my invention.
